Mandiant’s founder just raised $190M for his autonomous AI agent security startup

Cybersecurity legend Kevin Mandia, the mastermind behind the $5.4 billion sale of Mandiant to Google, is back in the game—and this time, he’s bringing the heat with an AI-powered startup that’s already making waves. Meet Armadin, the new kid on the cybersecurity block that just pulled off a jaw-dropping $189.9 million funding round, setting a record for the largest seed and Series A combo in the industry’s history. 🚀

Mandia, a globally renowned cybersecurity expert, isn’t just dipping his toes into the AI waters—he’s diving in headfirst. With Armadin, he’s building autonomous cybersecurity agents designed to learn, adapt, and respond to threats without human intervention. Think of it as an AI-powered army of white hats, ready to take on the looming threat of AI-driven cyberattacks from the black hats. 🤖⚔️

The funding round was led by Accel, with heavy hitters like GV, Kleiner Perkins, Menlo Ventures, 8VC, Ballistic Ventures, and even the CIA’s venture arm, In-Q-Tel, jumping on board. While other security startups have raised bigger Series A rounds, none have done it at this early stage. For context, 1Password and OneTrust both raised $200 million in Series A funding, but they were already years into their journeys. Armadin, on the other hand, is just getting started—and it’s already turning heads. 👀

Mandia’s co-founders are no slouches either. Travis Lanham, a former Google Cloud Security principal engineer, Evan Peña, a former Mandiant exec, and David Slater, a former Google SecOps engineer, round out the team. Together, they’re on a mission to level the playing field in the age of AI-powered cyber warfare.

In a recent interview, Mandia warned that autonomous AI hackers are on the horizon, and they’re not to be underestimated. “When you have AI on offense, what you are going to get is a technology that can think, can learn, can adapt,” he said. “Attackers will be able to complete attacks in minutes that used to take days.” Yikes. 😱

Armadin aims to counter this threat by giving defenders their own agentic armies—autonomous systems that can fight fire with fire. It’s a bold move in a world where the stakes are higher than ever, and the race to stay ahead of cybercriminals is relentless.

As Mandia puts it, “The future of cybersecurity isn’t just about humans fighting humans—it’s about AI fighting AI.” And with Armadin, he’s betting big on the good guys. 🎰

TechCrunch has reached out to Armadin for more details, but one thing’s for sure: this startup is one to watch. Whether you’re a cybersecurity pro, a tech enthusiast, or just someone who cares about staying safe online, Armadin’s story is a reminder that the future of security is here—and it’s powered by AI.
